[0028] Figure 6 This is a schematic diagram of the structure of a USB circuit board and insulating component according to an embodiment of the present invention. Detailed Implementation

[0029] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of specific ways of implementing and using this utility model, and are not intended to limit the scope of this utility model. The descriptions of the structural positions of various components, such as up, down, left, right, etc., are not absolute but relative. These directional descriptions are appropriate when the various components are arranged as shown in the figures, but they change accordingly when the positions of the components in the figures change.

[0030] The dimensions of wall power outlets and the required wall space for their installation are fixed according to different national standards. Power outlets typically have a power interface for plugging in electrical devices. With the rise of mobile phones and laptops, USB charging ports can be directly added to existing power outlets, eliminating the need for a power adapter.

[0031] Figure 1a and Figure 1b A schematic diagram of wall power sockets (hereinafter referred to as "sockets") 100a and 100b according to an embodiment of the present invention is shown. Figure 1a The power socket 100a includes two power interfaces 13 and 14, two USB interfaces 15, and two switch buttons 11 and 12 that control the connection and disconnection of the current to the two power interfaces respectively. The two power interfaces 13 and 14 are located on both sides of the socket, and the USB interface is located slightly above the middle of the two power interfaces. Both USB interfaces on the socket 100a are Type-C interfaces. Figure 1b The power socket 100b and Figure 1aThe power socket 100b is similar to the 100a, differing only in the shape of the power connector and the type of USB connector. The 100b has two Type-A connectors 16 and one Type-C connector. It can be understood that the USB connectors on the socket can be other combinations of Type-A and Type-C connectors, such as two Type-A connectors, one Type-A connector plus two Type-C connectors, etc.

[0032] Once a USB port on the socket is connected to a power source, it remains powered on and is not controlled by a power switch. Due to space limitations of power sockets, the USB charging circuit board is relatively small, resulting in a lower charging power output from the USB charging port, typically around 30W. This is insufficient for charging high-power devices such as laptops.

[0033] To address the aforementioned problems, one embodiment of this utility model provides a wall power socket, including a panel and a base. The base contains a first cavity and second and third cavities located on either side of the first cavity. A circuit board assembly is housed in the first cavity, a first electrical contact assembly is housed in the second cavity, and a second electrical contact assembly is housed in the third cavity. The first electrical contact assembly converges towards the second cavity in a direction away from the first cavity, such that at least a portion of one side of the first cavity extends into the second cavity. The second electrical contact assembly converges towards the third cavity in a direction away from the first cavity, such that at least a portion of the other side of the first cavity extends into the third cavity.

[0034] Figure 2 A schematic diagram of the base of a wall power socket according to an embodiment of the present invention is shown. Figure 3 An exploded view of the metal component of a wall power socket according to an embodiment of the present invention is shown. Figure 4 An assembly diagram of the metal parts of a wall power socket according to an embodiment of the present invention is shown. Figure 5 An exploded perspective view of a wall power socket according to an embodiment of the present invention is shown. Figure 6 A schematic diagram of the structure of a USB circuit board and insulating component according to an embodiment of the present invention is shown.

[0035] exist Figure 2 The base 50 contains a first cavity 51 and a second cavity 52 and a third cavity 53 located on both sides of the first cavity 51. The first cavity 51 is an irregular cuboid, with its two side edges protruding into the second cavity 52 and the third cavity 53, respectively. Figure 2 The image shows that most of the upper edges of the two sides of the first cavity 51 protrude to both sides.

[0036] The first cavity 51 houses a circuit board assembly, the second cavity 52 houses a first electrical contact assembly 41, and the third cavity 53 houses a second electrical contact assembly 42. The first electrical contact assembly 41 and the second electrical contact assembly 42 respectively provide two prongs for the socket. The wall power socket also includes an electrical connection assembly 40. The first electrical contact assembly 41 and the second electrical contact assembly 42 are connected via the electrical connection assembly 40.

[0037] exist Figure 3 In this configuration, the first electrical contact assembly 41 converges to the left. This convergence refers to retracting towards itself to make way for adjacent components. The first electrical contact assembly 41 converges towards the second cavity 52 in a direction away from the first cavity 51, such that at least a portion of one side of the first cavity 51 extends into the second cavity 52. ​​Thus, the upper portion of the left edge of the first cavity 51 extends into the second cavity 52.

[0038] exist Figure 3 In the middle, the second electrical contact assembly 42 converges to the right. The first electrical contact assembly 42 converges towards the third cavity 53 in a direction away from the first cavity 51, such that at least a portion of one side of the first cavity 51 extends into the third cavity 53. Thus, the upper portion of the right edge of the first cavity 51 extends into the third cavity 53.

[0039] Because the first electrical contact assembly 41 and the second electrical contact assembly 42 converge on both sides of the first cavity 51 in a direction away from the first cavity 51, the edges of the first cavity 51 are not regular rectangles. Compared to a conventional cavity, the space on both sides of the upper part of the first cavity 51 can extend to both sides, thereby increasing the internal space of the first cavity 51. This increases the area of ​​the USB circuit board located in the first cavity, thereby improving the charging power of the USB circuit board.

[0040] exist Figure 3 In this configuration, electrical connection assembly 40 connects the first electrical contact assembly 41 and the second electrical contact assembly 42. Electrical connection assembly 40 includes a first connecting metal member 40A and a second connecting metal member 40B. Figure 3 In the example, the upper first connecting metal piece 40A is used to connect the live wire pin of the left and right plugs, and the lower second connecting metal piece 40B is used to connect the neutral wire pin of the left and right plugs. Furthermore, the first connecting metal piece 40A and the second connecting metal piece 40B are arranged parallel to each other. Both the first connecting metal piece 40A and the second connecting metal piece 40B are metal sheet structures, and their extended planes are parallel to the plane of the panel 10.

[0041] like Figure 3As shown, in some examples, the first connecting metal member 40A includes a U-shaped structure protruding towards the second connecting metal member 40B. In other examples, the second connecting metal member 40B includes a U-shaped structure protruding towards the first connecting metal member 40A. The U-shaped structure can reduce the distance between the first connecting metal member 40A and the second connecting metal member 40B. The bending angle of the U-shaped structure is ninety degrees. It can be understood that in other examples, the bend on the first connecting metal member 40A or the second connecting metal member 40B can be a non-perpendicular bend.

[0042] The convergence of the first electrical contact assembly 41 and the second electrical contact assembly 42 in a direction away from the first cavity 51 can be achieved through the optimized layout of their structures.

[0043] In some examples, such as Figure 3 As shown, the first electrical contact assembly 41 includes a first neutral wire pin 411, a first live wire pin 412, a first ground wire pin 413, a first neutral wire connecting piece 414, a first live wire connecting piece 415, and a second live wire connecting piece 416.

[0044] One end of the first neutral wire connector 414 is connected to the first neutral wire pin 411, and the other end of the first neutral wire connector 414 is connected to the second connecting metal part 40B. One end of the first live wire connector 415 is connected to the first live wire pin 412, and the other end of the first live wire connector 415 is connected to one end of the second live wire connector 416. The other end of the second live wire connector 416 is connected to the first connecting metal part 40A.

[0045] The first live wire connector 415 includes a multi-segment bent structure. The extended plane of the bent structure near one end of the first live wire connector 415 is perpendicular to the panel 10. Specifically, the left and right parts of the first live wire connector 415 are L-shaped metal pieces. The left L-shaped metal piece is connected to the second live wire connector 416, and the right L-shaped metal piece is connected to the first live wire pin 412. Both of these L-shaped metal pieces are inverted L-shapes, similar in shape to the number 7.

[0046] Additionally, see Figures 3-4 The extended plane of the L-shaped metal piece on the left side of the first live wire connector 415 is parallel to the panel 10, while the extended plane of the L-shaped metal piece on the right side of the first live wire connector 415 is perpendicular to the panel 10. The structure of the first live wire connector 415, especially the metal piece near the live wire pin, can reduce the space occupied by the second cavity 52, thereby making room for the left side of the first cavity 51.

[0047] In some examples, such as Figure 3As shown, the second electrical contact assembly 42 includes a second neutral wire pin 421, a second live wire pin 422, a second ground wire pin 423, a second neutral wire connecting piece 424, a third live wire connecting piece 425, and a fourth live wire connecting piece 426. The first neutral wire pin 411, the first live wire pin 412, the first ground wire pin 413, the second neutral wire pin 421, the second live wire pin 422, and the second ground wire pin 423 may include a spring-loaded structure for inserting and removing the plug of an external electrical appliance.

[0048] One end of the second neutral wire connector 424 is connected to the second connecting metal piece 40B, and one end of the second neutral wire connector 424 is provided with a second neutral wire pin 421. One end of the third live wire connector 425 is connected to the second live wire pin 422, and the other end of the third live wire connector 425 is connected to one end of the fourth live wire connector 426. The other end of the fourth live wire connector 426 is connected to the first connecting metal piece 40A.

[0049] The second neutral wire connector 424 includes a multi-segment bent structure. From Figures 3-4 The second neutral connecting piece 424 is an L-shaped metal sheet that has been flipped over. The extended planes of the metal sheet at one end of the second connecting metal sheet 40B and the metal sheet at the other end away from the second connecting metal sheet 40B are parallel to the panel 10, while the extended plane of the upward-bent structure in the middle of the second neutral connecting piece 424 is perpendicular to the panel 10. The structure of the second neutral connecting piece 424, especially the part of the metal sheet with the upward-bent structure in the middle, can reduce the space occupied by the third cavity 53, thereby making room for the right side of the first cavity 51.

[0050] Figure 3 The electrical connection component 40, the first contact component 41, and the second contact component 42 are different components, but some of them can be integrally molded. For example, as... Figure 3 As shown, the first neutral wire pin 411, the first neutral wire connecting piece 414, the second connecting metal piece 40B, the second neutral wire pin 421, and the second neutral wire connecting piece 424 are integrally formed. Similarly, the second live wire connecting piece 416, the first connecting metal piece 40A, and the fourth live wire connecting piece 426 are integrally formed. In other examples, the multi-segment structure of the electrical connection assembly 40, the first contact assembly 41, and the second contact assembly 42 can be combined by mechanical connection. Figure 3 The one-piece molding in the example can reduce manufacturing complexity.

[0051] In some embodiments, a slot can be provided on the base to secure the USB circuit board 20, thereby separating it from the metal component. In other embodiments, an insulating component can be provided between the USB circuit board 20 and the metal component.

[0052] Now for reference Figure 5 , Figure 5 An exploded perspective view of a wall power socket 100 according to an embodiment of the present invention is shown. The wall power socket 100 includes a panel 10, a USB circuit board 20, an insulator 30, and a base 50. The panel 10 is located on the surface of the socket 100 and has through holes corresponding to a USB interface, a power interface, and a switch. The base 50 is located on the back of the socket 100. The space between the panel 10 and the base 50 is sufficient to accommodate the USB circuit board 20, the insulator 30, and a metal component. The insulator 30 is used to insulate the USB circuit board 20 and the metal component. The metal component includes an electrical connection assembly 40, a first contact assembly 41, and a second contact assembly 42.

[0053] Figure 6 A schematic diagram of a USB circuit board 20 and an insulating member 30 according to an embodiment of the present invention is shown. The USB circuit board 20 is located above the insulating member 30. The insulating member 30 is made of an insulating material, such as plastic. The insulating member 30 has an open cuboid structure, and the bottom of the insulating member 30 is a plate-shaped body 34, with plates perpendicular to it around the perimeter. The recessed portion of the insulating member 30 is used to accommodate the USB circuit board 20. The plate-shaped body 34 is used to separate the USB circuit board located on one side of the insulating member 30 from the electrical connection assembly 40 located on the other side of the insulating member 30. The plates perpendicular to the perimeter of the insulating member 30 can separate the USB circuit board 20 from the first electrical contact assembly 41 and the second electrical contact assembly 42.

[0054] Specifically, the plate-shaped body 34 is located between the USB circuit board 20 and the electrical connection assembly 40, and from the rear view of the socket, the plate-shaped body 34 covers the USB circuit board 20. Since the electrical connection assembly 40 is located on the back of the USB circuit board 20, it does not need to occupy space on the extended plane of the USB circuit board 20. Furthermore, the first electrical contact assembly 41 and the second electrical contact assembly 42 converge to both sides. These features increase the area of ​​the USB circuit board, allowing for the placement of more components. The charging power of the USB circuit board can be increased to 45W or even 65W. This improves charging efficiency when the socket is used to charge mobile phones. The socket can also charge high-power devices such as laptops.

[0055] In some implementations, the USB circuit board draws power through soldering. Specifically, the contacts on the USB are connected to the conductive plates of the live and neutral wires via soldered wires. This method requires manual soldering of the wires when installing the socket, which is not conducive to automated production.

[0056] Figure 6In the example, the back of the USB circuit board 20 is provided with a neutral power pin 21 and a live power pin 22. Correspondingly, the plate-shaped body of the insulating member 30 is provided with a first through hole 31 and a second through hole 32. The neutral power pin 21 can pass through the first through hole 31 to contact the second connecting metal member 40B, and the live power pin 22 can pass through the second through hole 32 to contact the first connecting metal member 40A.

[0057] The neutral power pin 21 and the live power pin 22 are equipped with springs. When the USB circuit board 20 is fixed, the springs are compressed, and the neutral power pin 21 and the live power pin 22 press against the corresponding metal parts, which can prevent shaking and ensure good contact. Figure 2 The image shows that the USB circuit board 20 can be mounted on the screw post 54 of the base by screws.

[0058] Now back Figure 4 Because of the U-shaped structure protruding from the first connecting metal part 40A to the second connecting metal part 40B, the distance between the first connecting metal part 40A and the second connecting metal part 40B is reduced, making it easier for the neutral wire power pin 21 and the live wire power pin 22 to draw power.

[0059] Figure 4 A first metal sheet 90 and a second metal sheet 91 are also shown. The bending of the first connecting metal member 40A allows for clearance of the first metal sheet 90, thereby increasing its area. See also... Figure 5 The base 50 has heat dissipation holes 55 corresponding to the positions of the first metal plate 90 and the second metal plate 91. The heat dissipation holes 55 include a plurality of densely arranged small holes. The first metal plate 90 and the second metal plate 91 are located in front of the heat dissipation holes 55. In this way, the heat generated by the USB circuit board 20 is conducted to the outside of the heat dissipation holes 55 via the first metal plate 90 and the second metal plate 91. The first metal plate 90 and the second metal plate 91 can be made of copper, aluminum, or other metal materials. Furthermore, these two metal plates 90 and 91 are located in the same plane. This plane can be parallel to the plate-shaped body 34 of the insulating member 30 and the USB circuit board 20. In this way, the USB circuit board 20, the plate-shaped body 34, and the electrical connection assembly 40 can be fitted together, saving internal space in the socket 100 as much as possible.

[0060] Now for reference Figure 6 The bottom of the USB circuit board is also equipped with a shielded power pin 23, and the plate-shaped body 34 of the insulating component 30 is also equipped with a third through hole 33. The shielded power pin 23 passes through the third through hole 33 and contacts the first metal plate 90. This arrangement can shield the power module on the front side of the USB circuit board from EMI interference.

[0061] Figure 5The diagram shows an intermediate panel 60 between the front panel 10 and the USB circuit board 20 in the socket 100. Similar to the front panel 10, the intermediate panel 60 has through holes corresponding to the USB interface, power interface, and switch, and these through holes are positioned to match the through holes on the front panel 10. The intermediate panel 60 is installed inside the front panel 10. The front panel 10 and the intermediate panel 60 can be fixed together by snap-fit, and the intermediate panel 60 and the base 50 can be fixed together by rivets. Compared to rivet connections, snap-fit ​​connections are easier to disassemble. When the socket 100 needs to be installed on a wall of a different color, a different colored front panel 10 can be used to match the wall color.

[0062] The surface of the middle panel 60 has a recess 61 that avoids the locations of power interfaces 13, 14 and power switches 11, 12. A heat sink 62 is housed within the recess 61. The heat sink 62 avoids the locations of USB interfaces 15, 16. In some examples, the heat sink includes one or more of graphene heat sinks, graphite heat sinks, and metal heat sinks.

[0063] The USB circuit board 20 is equipped with a USB interface and other components (not shown in the figure). The position of the USB interface corresponds to the position of the through hole on the front panel 10 and the middle panel 60. The terms "front," "rear," or "back" in this utility model refer to the socket in the installed state.

[0064] Now for reference Figures 3-4 The second live wire connector 416 is also used for connecting to an external live wire. A protruding live wire connector 418 is provided near the end of the second live wire connector 416. The socket 100 also includes a live wire terminal 92, through which the live wire connector 418 is connected to an external live wire.

[0065] The second neutral wire connector 424 is also used to connect to an external neutral wire. A neutral wire connector 428 is provided at the other end of the second neutral wire connector 424, i.e., the end furthest from the second neutral wire pin 421. The socket 100 also includes a neutral wire terminal 93, through which the neutral wire connector 428 is connected to an external neutral wire.

[0066] The socket 100 also includes a switch for controlling the power supply to the two prongs. See [link / reference needed]. Figure 3 The socket 100 also includes a first moving contact 95 and a second moving contact 96.

[0067] The other end of the first live wire connector 415 is provided with a first fixed contact 419, and the other end of the third live wire connector 425 is provided with a second fixed contact 429. The first fixed contact 419 is bent to the left at the end of the first live wire connector 415 to form an L-shape. The second fixed contact 429 is bent to the right at the end of the third live wire connector 425 to form an L-shape. Here, left and right are based on the view from the front of the socket facing the socket.

[0068] One end of the second live wire connector 416 is provided with a first support piece 417, which is configured to support the first movable contact piece 95. The other end of the fourth live wire connector 426 is provided with a second support piece 427, which is configured to support the second movable contact piece 96. The first support piece 417 is bent upward at one end of the second live wire connector 416 to form an L-shape. The second support piece 427 is bent upward at the end of the fourth live wire connector 426 to form an L-shape. These bending structures can reduce the space occupied.

[0069] The first movable contact 95 is configured to connect or disconnect from the first fixed contact 419 when toggled by the first switch button 11. The second movable contact 96 is configured to connect or disconnect from the second fixed contact 429 when toggled by the second switch button 12.

[0070] Now for reference Figure 5 The socket 100 also includes a grounding metal piece 71 located on the rear side of the base 50, with both ends connected to the first grounding pin 413 and the second grounding pin 423. The grounding metal piece 71 is also provided with a grounding connecting piece 713. The grounding connecting piece 713 is connected to an external grounding wire via a grounding terminal 94. Figure 5 In the example, the grounding metal part 71 has two symmetrical live wire terminals 94.
